First Quarter in Taurus

First Quarter on . The illuminated surface of the moon is 50% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 9 February 2003 at 11:11 UTC.

Moonrise and moonset

The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon phase and lunation details

Moon in ♉ Taurus

Moon is passing about ∠21° of ♉ Taurus tropical zodiac sector.

Snow Moon after 7 days

Next Full Moon is the Snow Moon of February 2003 after 7 days on 16 February 2003 at 23:51.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1774"

Lunar disc appears visually 9.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1774" and ∠1945".

Lunation 38 / 991

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 38 of Meeus index or 991 from Brown series.

Synodic month length 29.66 days

The length of this lunation is 29 days, 15 hours and 47 minutes and it is 57 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 3 hours and 3 minutes longer than the mean synodic month length. It is 4 hours shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠90.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠90.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠127.8°.

Moon after apogee

1 day since point of apogee on 7 February 2003 at 21:58 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 19 February 2003 at 16:19 in ♍ Virgo.

Distance to Moon 404 010 km

The Moon is 404 010 km (251 040 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 364 844 km (226 704 mi).

Moon before ascending node

12 days after descending node on 27 January 2003 at 15:23 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 10 February 2003 at 17:39 in ♉ Taurus.

Moon before northern standstill

10 days since the last southern standstill on 30 January 2003 at 00:31 in ♑ Capricorn when the Moon has reached South declination of ∠-25.834° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠25.923° at the point of next northern standstill on 13 February 2003 at 10:59 in ♋ Cancer.

Draconic month

25 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 16 February 2003 at 23:51 in ♌ Leo the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
